Now that we are getting comfortable with chain rule, try one other. {{CMD_61}} Suppose {{MATH_62}} is a function whose values are given in the following table. {{CMD_63}} {{ENV_64}} {{CMD_65}} Find {{MATH_66}} {{CMD_67}} At it's outer most level, this is a product of {{MATH_68}} and {{MATH_69}}, so we start with product rule. {{ENV_70}} Evaluating at {{MATH_71}} gives: {{ENV_72}} {{CMD_73}} {{CMD_74}}
